Notes from the porch, after the call

These are written to be read by the person who owns the appliance, not by someone who repairs them for a living. Where a fault has a cheap explanation and an expensive one, both are named, and the cheap one is checked first.

New notes appear here as they are written. There is an RSS feed if you would rather not come back and look.
